SU LKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 476,579, dated J une7', 1892.

Application filed February 15, 1892. Serial No. 421,580. (No model.)

To all whom, it may concern:

Be it known that I, SAMUEL H. TINsMnN, a citizen ot' the United States,residing at Morris, in the county of Grundy and State of Illinois, haveinvented certain new and useful Improvements in Sulky-Plows; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

My invention relates to improvements in plows, and relates especially towhat may be termed sulky or riding7 plows.

One object of myinventionis the provision of a plow which will be lightin weight, so as to be easily drawn over the ground, which will comprisefew parts, rendering the same simple and durable in construction, andconsequently comparatively inexpensive of production.

Another object of my invention is the provision of a plow which can beeasily manipulated by one person to cause the point to make a furrow ofany desired depth or be thrown out of operation, as may be desired.

Another object of my invention is the provision of a durable, cheap, andeffective plow which will be compact and light in weight and in whichthe operative element or part can be folded to occupya small space,whereby the plow can be readily and easily transported.

To attain the desired objects the invention consists ot' a plowembodying novel features of construction, combination, and arrangementof parts for service, as will be disclosed herein.

In order that the construction, operation, and advantages of my improvedplow may be readily understood, l have illustrated my invention in theaccompanying drawings, in which- Figure l represents a perspective viewof a plow constructed according to my invention, the parts being shownin full lines in operative position and in dotted lines as they appearwhen not in use; and Fig. 2 represents a top plan view of the plow.

Referring by numerals to the drawings, 1 designates the frame of myplow, comprising the two parallel longitudinal bars, preferably formedof metal and having the ends connected by the plates 2 and 3.

Projecting laterally from the forward end of the frame is the bracket orarm 4, in which is mounted the shaft 5, having the bearings for thesupporting-wheel 6, and on the end of said shaft is secured the plate orclevis 7, to which the draft-pole 8 is connected. Also on said shaft issecured the sprocket-wheel 9, over which passes the sprocket-chain 10and from thence to the sprocket-wheel 1l, carried by the shaft 12,having the rear supportingwheel 13. To the opposite side of the frame issecured the axle 14, on which is mounted the supporting-wheel 15, saidaxle being suitably braced to the main :trame and also receiving theseat-support 16, carrying a seat 17. From this construction it will beseen that l provide a light and durable trame which is properlysupported, with the forward supporting-wheel out of the path of theplow, and that the supporting-wheels are movable and so connected thatthe plow may be guided or turned in any direction, as may be founddesirable and convenient.

Secured to the frame is the curved rack-bar 1S, and below the same thecurved plate 19, to which is piveted the hand-lever 20, adapted to beadjusted and retained at any point on the rack-bar by means of thespring-detent 21. To the lower end of the lever is connected the arm 22,which arm is connected to the bar 23, carrying the plow-point 24, andsaid arm 28 is pivoted to the upright 25, which is securely braced bythe inclined bar 26, secured to the frame, as shown. From thisconstruction it will be seen that the hand-lever is within easy reach ofthe driver and can be operated to cause the plow to enter the ground toany desired depth or to elevate the plow ont of position for use, as isevident. Connected to said lever near the lower end is the rod 27, thelower end of said rod being connected to the arm 2S, carrying thecolter-wheel 29, arranged slightly in advance of the plow, and it willbe observed that by reason of its connection with its hand-lever it willbe thrown into position for use or out of use, accordingly as the plowIOO is used. The colter-wlieel is swiveled at 28X, and can thus be movedwhen desired andlield by the set-screw 28M.

It is evidentl that l provide n plow which is light of draft and whichcnn be easily controlled by the operator or user to plow to zing7desired depth or be thrown ont of operation. and be guided or turnedwith ense in any direction. It is also evident that l provide n plowwhich is strong, durable, and effective,

which can be easily and readily transported from any place, and which isinexpensive, thus possessing all the fee-tures oi merit to commend theplow as practicable and useful.

l claim as my inventionl. A plow consisting of a freine, thebracketcxtendng outward therefrom, the shaft carrying` thesupporting-wheel and mounted tl1erein, the sprocket-wheel carried byseid shaft, the shaft carrying the supporting-wheel and sprocket-wheeland nionnted at the renrot the frame, the sprocket chain engaging saidsprocket-wheels, the axle carrying the snpporting-wheel, the verticaland inclined bracebars having' their npger ends connected to the frameand their lower ends adjacent, forming' n rigid frame, the short bnrconnected to the vertical brace it one end, the plow-point connected tothe other end of the short bnr, the

vertical hand-lever,having its lower end connected to the plow-point thecolter-arni pivoted to the frame, and the rod connecting the rm andhand-lever, substantially as dcscribed.

i. A plow consisting of a frame, the suppo rtin g-wli eel, the sprocketwheels an d chain, the curved rack-bnr secured to thcfrzmne,tl1e pletesecured to the traine, the lever pivot-ed to saidV plete and carryingthe spring-detent for engaging the raclsber, the erin or bar connectedto said lever, the plow connected to said nrin or bar, the verticalbrace-arm connected to said bnr and the traine, the inclined brace-barconnected to the frame and the vertical bar, the rod pivoted Vto theframe, the rod carrying the colter-wheel and swiveled in said rod, thescrew for securing the rod, and the rod connected to the hand-lever andswiveled rod, all adapted to operate ns described.

In n plow, the combination of the vertically-movable arm with the armcarrying the colter-whcel and swiveled to the verticallymovable arm,zuid a set-screw for retniningtlic swiveled colter-arn'i.

in testimony whereof l nilix my signature in `grcscnce ot' twowitnesses.
